Burgess gradbaReason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
There is a flip plate at the top of the bridge deck, which is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
Burgess gradbach.Usage scenario: Widely applicable for installation, maintenance, and high-altitude work platform vehicles in industries such as municipal administration, electricity, streetlights, advertising, communication, photography, landscaping, transportation, docks,Burgess gradbachFixed hydraulic boarding bridge,Burgess gradbachDengCheQiao Manufacturing Factory, airports and ports and large industrial and mining enterprises.
During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.
.Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, the relief valve gets stuck or severely worn, and the fatigue deformation of the relief valve spring leads to unstable pressure regulation of the relief valve. The pressure release time of the relief valve is too short which can easily lead to local stability of the pilot valve performance of the relief valve. Noise is generated by the vibration of the pilot valve's air. Therefore, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
Portable hydraulic press boarding bridge: It is a widely used type, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc
It is strictly prohibited to apply excessive pile loads around the foundation pit.
Curved arm aerial work platform vehicle.
The platform side boarding bridge is directly installed at the front edge of the loading and unloading platform. There is no need to excavate or reserve pits on the loading and unloading operation platform, and there is basically no change to the building structure.
Packaging strategy.Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing), indicator light on press the up button, overflow valve pressure is low lowering valve is open, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
Slowly reverse and park the container under the lip at the front of the boarding bridge.
Open the manual valve, slowly lower the boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
Is the boarding bridge easy to use? Those who have used the boarding bridge know that it is a very useful mechanical equipment, which brings great convenience to the logistics industry and some industrial factories that need to load and unload goods. Some enterprises also value the development prospects of the boarding bridge and set up factory boarding bridges. High priced and various specifications of boarding bridge manufacturers provide timely supply, with high cost-effectiveness, and has become the preferred brand for many wire products. Welcome to choose!
Information recommendation.The user department of the hydraulic boarding bridge should scientifically analyze the equipment and reasonably determine the investment in the equipment. At the same time, according to the characteristics of the work,Burgess gradbachLifting and disembarking bridge, professional personnel should be arranged to carry out on-site maintenance and upkeep to ensure that the lifting platform truck is always in normal operation, ensuring timely loading and unloading of supplied materials; The normal operation of equipment needs to be guaranteed by institutional measures, strengthen dynamic management of equipment faults, monitor the status of key parts, and analyze the patterns of faults through maintenance; It is necessary to ensure the supply of maintenance accessories, establish a spare parts warehouse for vulnerable and commonly used parts, and purchase channels to avoid situations where inadequate preparation may lead to extended downtime and increased repair costs; Users should maintain a close relationship with survival manufacturers, strengthen the professional quality and professionalism of lifting platform maintenance personnel, so that they can handle faults in a short period of time.
Applicable scenario: Suitable for mobile high-altitude operations such as setting and inspection of high-altitude equipment in various industries.
conduct.
Burgess gradbach.To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.
The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.
After the boarding bridge work is completed, all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.
